Skim Crepe 

Skim crepe rubber is a low-cost by-product produced during latex centrifuging process. Therefore, it has a dry rubber content of only 3 to 7%, however, it has a very low dirt content which can be used in several applications, including trolley wheels, car mats, flaps, shoe soles, rubber tiles, to reduce material cost.

There are three different grades classified according to the colour and its purity: yellow, brown, and black
